Title:
PENDULUM ARM TYPE HIGHLY SENSITIVE AUTOMATIC ALIGNING WEIGHTED ARM CONSTRUCTION
Document Type and Number:
Japanese Patent JPS5281138
Kind Code:
A
Abstract:
The load arm (A) carries two driven rollers (RR, R') at one end and at its other end is supported on the housing (B, O), for example via a knife-edge mounting, in such a way that it is spherically pendulous about this point of articulation (O). The load arm is thus pivotable about a vertical axis, about a longitudinal axis and about a transverse axis. The load arm (A) is pressed via its rollers (R, R') against a drive body (D) by means of spring force (S). The free movability of the load arm (A) has hitherto been adversely influenced by this pressure force (S). In order to avoid this, a rolling body (K) is arranged between the pressure spring (S) and the load arm. The disturbing influence caused by spring deflection is prevented by this rolling body (K). The rolling body (K) is located in a U-shaped cap (HB) which is supported on the spring (S). The rolling body (K) rolls on the cap and on the load arm.
